(Abstract base class )
Description
This is an abstract base class that represents an abstract page heap buffered through a set of
memory buffers. It inherits from the abstract base class RWVirtualPageHeap, which represents
an abstract page heap.
RWBufferedPageHeap will supply and maintain a set of memory buffers. Specializing classes
should supply the actual physical mechanism to swap pages in and out of these buffers by
supplying definitions for the pure virtual functions swapIn(RWHandle, void*) and
swapOut(RWHandle, void*).
The specializing class should also supply appropriate definitions for the public functions
allocate() and deallocate(RWHandle).
For a sample implementation of a specializing class, see class RWDiskPageHeap.
